FOREWORD its inception, the Division of Research Grants and Fellowships of the National Institutes of Health has endeavored whenever possible and feasible to fulfill its prime objectives of coordination, promotion, and stimulation of research, particularly in neglected areas. It is the earnest belief of the Experimental Therapeutics Study Section that in this Dictionary of Antibiosis lies a gratifying measure of achievement of part of these objectives as related to a small but nevertheless significant facet of medical research. SINCE

It is hoped that this volume will attain the usefulness envisioned for it and that it will be a source of real assistance to those who may choose to use it. Chairman Experimental Therapeutics Study Section National Institutes of Health WALSH M C D E R M O T T ,

PREFACE of this dictionary the term antibiotic is defined as a substance derivable from living organisms and capable of adversely modifying the vital functions of specific microorganisms. The data included are arranged alphabetically and consist of ( 1 ) compilation of substances tested for antibiotic activity; ( 2 ) available information on source, extraction, chemical and physical properties, spectrum in vitro and in vivo, toxicological and pharmacological, clinical and experimental clinical results; and (3) enumeration of organisms (designated as test organisms) against which substances have been tested for antibiotic activity. Under each of the test organisms there are given, wherever applicable, the species tested against it for antibiosis, and the named antibiotics similarly tested against it or, where very long lists of substances have been tested for antibiosis and appear in one paper, the bibliographic reference only. The bibliography is arranged alphabetically, according to authors, with appropriate cross-references, and cites the complete title of each paper recorded. It has not been practicable routinely to include strain designations. For precise information regarding these designations, the bibliographic references to the individual species should be consulted. Neither has it been practicable to include two of the older antibiotics—ethyl alcohol and quinine, and only brief sketches have been given for penicillin and streptomycin, both of which have been adequately covered by other authors.

Susceptible strains of yeasts readily develop resistance to actidione [7], A series of in vitro tests with actidione in concentrations varying from 0.001 mg to 0.008 mg/cc against Cryptococcus neoformans resulted in killing the various strains used [11], TOXICITY.—The L D G O in rats is 2.7 mg/kg s.c. or 2.5 mg/kg i.V.; in cats, 4 mg/kg ¡.p.; in rabbits, 17 mg/kg i.V.; in guinea pigs, 60 mg/kg s.c. [4, 6]; in mice, 150 mg/kg i.v. [3, 4, 6]. Actidione killed mice given 2 mg/day (100 to 150 m g / k g ) in 5 days, and mice given 1 mg/day (50 to 75 m g / k g ) in 8 to 12 days, but it was tolerated without signs of toxicity when administered in doses of 0.1 and 0.2 nig-'day [11], A BSORPTION. — Actidione is rapidly absorbed after i.p. inj in rat, dog, and guinea pig, and is demonstrable in the plasma for at least 90 min [10]. EXPERIMENTAL CLINICAL RESULTS. —When administered to mice which have had inoculations of 90,000 organisms of one of the strains of Cryptococcus neoformans, actidione was without demonstrable effect when given in doses of 1 mg i.m. or s.c. to 4 mice, and in doses of 0.2 mg to 4 additional mice. Against another strain of cryptococcus administered to mice i.v. in an inoculation of 660,000 organisms, actidione likewise had no effect. In this instance 5 mice were put on a dosage schedule of 0.2 mg/day i.m. and i.v. and an

additional S mice were given 1 mg/day. Treatment consisted of inj of the drug twice a day for 5 days and once a day for 14 days. The animal» on larger doses of the drug apparently experienced cumulative toxic effects since they were sicker than the controls. In man, actidione was used in only one patient and proved ineffective. Cultures of the spinal fluid, however, showed marked reduction in the number of cryptococci present in the fluid itself. This suggests an in vitro fungicidal effect providing the drug can be brought into direct contact with the infecting agent, especially since it was found that serum does not inactivate the drug [11].

Actinomycetin is nontoxic or very slightly toxic t o experimental animals [ 1 ]. See [ 1 ] Waksman, 1945; [2] Hoogerheide, 1944. actinomycin, a crystalline antibiotic isolated f r o m the culture filtrates of Actinomyces (Streptomyces) antibioticus [1J and other Streptomyces spp. [ 2 , 3 , 4 ] . It was formerly thought [1J that the activity occurred in two fractions, A and B, having different antimicrobial actions; investigators now believe that the activity of the so-called "actinomycin B" is due to contamination with the A fraction [3], T h e antibiotic is extracted f r o m the filtrates with ethyl ether, petroleum ether, ethanol, and chloroform [5J, and purified by chromatographic adsorption and recrystallization [6J. T h e active vermilion-red platelets, m.p. 2 5 0 ' C . (decomp.) [6], are soluble in ethyl ether, ethanol [1, 5, 6J, water LI. 6], carbon disulphide [5], acetone, chloroform [5, 6 J, benzene, hot ethyl acetate, and 10 p e r c e n t hydrochloric acid [6J; and insoluble in petroleum ether [1J and dilute aqueous acids and alkalis [ 6 j . T h e mol. wt. is 768-1,000 [6]- Actinomycin is stable to light and does not lose activity when subjected to boiling for 30 min. [6J. It is most stable in neutral or slightly acid solution, but activity lost through alkalinization is restored by subsequent neutralization [5], SPECTRUM.—The following microorganisms are inhibited in vitro by 0.05-0.2 m g / c c : Aspergillus Candida [5] Aspergillus niger [5] Azotobacter [5] Bacillus megatherium [7] Bacillus mesentericus [7] Bacillus mycoides [5, 6, 7] Bacillus subtilis [ 5 , 6 , 7 ] Diplococcus pneumoniae [7] Escherichia coli [4, 5 , 6 ] Flavobacterium sp.

[5] Sarcina lutea [5, 6] Staphylococcus aureus [7] Streptococcus pyogenes [7] Trichoderma sp. [5] White yeast [5 J Actinomycin also inhibits the following: Achromobacter stutzeri [1] Actinomyces californicus [1] Actinomyces cellulosae [1] Azotobacter vinelandii [l] Bacillus cereus [1] Bacillus macerans [11 Bacillus polymyxa [1] Brucella abortus [ 1 ] Clostridium welchii [ 1 ] Cryptococcus neoformans [8] Erwinia carotovora [ 1 j Gaßkya tetragena [lj Hemophilus pertussis [11 Mycobacterium tuberculosis [1] Neisseria catarrhalis [1 I Pseudomonas fluorescent [ 11 Shigella gallinarum 11 ' Trichophyton mentagrophytes [8]

Actinomycin is bactericidal for Br. abortus, E. coli [1, 5), B. subtilis [1], and Sarcina lutea [5]. It also inhibits the growth of tomato roots and causes cytolysis of Paramecium, Glaucoma, and Colpidium [7). The following organisms are not inhibited in vitro by actinomycin: Aerobacter aerogenes [5]. Aspergillus clavatus [8] Candida albicans [8J Corynebacterium pyogenes [7] Dematium sp.

actinorubln, an antibiotic derived f r o m an unidentified Actinomyces designated as Actinomyces A-105. It resembles A. erythreus, A. fradii, A. albosporeus, and A. californicus. T h e active material is purified by the same method used for LAVENDULIN. The assay of actinorubin is also the same as that of lavendulin. T h e m.p. of the helianthate derivative is 206°214°C. (corr., decomp.) [1]. Staphylococcus aureus is inhibited in vitro by 0.2-0.55 micrograms/cc [2], Escherichia coli also is inhibited by actinorubin [1]. TOXICITY— Mice weighing 17-19 gm survive i.v. injs of 0.25 mg for at least 14 days; 1.37 mg causes 100 percent mortality in 5 days. Survivors of large doses fail to gain weight normally or actually lose weight. At autopsy the kidney and liver are found to be damaged and the thymus and spleen are reduced in size. In some cases there is evidence of recovery from liver damage [2]. A BSORPTION.—Intraperitoneal injection of 1.3 mg of actinorubin in mice results in detectable quantities in the blood up to 75 min post inj. N o actinorubin is found in the blood as early as 15 min after administration of 3.43 m g to mice by stomach tube [2]. EXPERIMENTAL CLINICAL RESULTS. —When 17-19 gm mice are infected with 1 cc of a 10 ° dilution of Klebsiella pneumoniae, i.v. inj of 13.7 micrograms gives complete protection, and injection of 3.4 micrograms gives 60

See Osborn, 1943. allkin, a colorless liquid antibiotic obtained by steam distillation from crushed cloves of the garlic. Allium sativum [1]. Although the name "allicin" has been withdrawn because of possible confusion with a medicinal product on the market, no other name for this substance has been proposed [2].

Analysis suggests the empirical formula CcHioOSa with the probable structure: Allyl-S-S-Allyl or Allyl-S-O-S-Allyl [3] Allicin is unstable to heat, stable under refrigeration, unaffected by dilute acid, and inactivated by alkali [1], It is also inactivated by cysteine [3, 4], It is soluble in water, ethyl alcohol, benzene, and ether [1]. Pure allicin has a garlic odor and is irritating to the skin [H. Allicin is effective in vitro against Streptococcus hemolyticus at 1:85,000 and the following organisms at 1:125,000 [1J: Bacillus subtilis Proteus morgani Salmonella enteritidis Salmonella paratyphi Salmonella schottmuelleri Salmonella typhi Salmonella typhimurium Shigella dysenteriae Shigella paradysenteriae Staphylococcus aureus Streptococcus viridans Vibrio cholerae Inhibition of Streptomyces griseus at 1:10,000, Aspergillus fumigatus and Penicillium cyclopium at 1:25,000, and the following organisms at 1:48,000 is also reported [5]: Aerobacter aerogenes Bacillus subtilis Escherichia coli Mycobacterium phlei Mycobacterium tuberculosis hominis Salmonella hirschfeldii Salmonella paratyphi Staphylococcus aureus The L D 5 0 for mice is about 60 mg/kg i.v. and 120 mg/kg s.c.

It is extracted from the culture medium by adsorbing on charcoal, eluting with a butanol-hydrochloric acid mixture, extracting into water, and converting to the picrate and finally to the hydrochloride. Alvein hydrochloride is soluble in water and ethanol; and insoluble in acetone, chloroform, and ether. Elementary analysis indicates the following composition for the hydrochloride: C, 49.0; H, 8.7; N, 12.9; S, 1.2; CI, 8.9. It is stable at rm. temp, at pH 2, 7, and 9. The activity is unaffected by boiling for one hr at pH 2; at pH 9, half the activity is destroyed by boiling for one hr. Trypsin destroys the activity, but horse serum has very little effect. Chemical tests indicate that the free substance is a strongly basic polypeptide. Alvein hydrochloride is hemolytic.

Anacardic acid is effective in vitro in inhibiting the growth of the following in the concentrations given: Organism Concentration Bacillus anthracis 1:20,000 Brucella melitensis 1:2,000 Mycobacterium tuberculosis (human strain "Ratti") 1:20,000 Neisseria gonorrhoeae 1:20,000 Pasteurella aviseptica 1:2,000 Penicillium nolatum 1:200 Proteus X-19 1:200 Staphylococcus hemolyticus aureus 1:20,000 Streptococcus pyogenes 1:200,000 Anacardic acid is ineffective in vitro in concentrations of 1:200 against the following: Asperillus niger Bacillus pyocyaneus Escherichia coli Salmonella paratyphi B Salmonella typhi Yeast (strain isolated from the air) The vegetative forms of anaerobic bacteria (Clostridium tetani, CI. perfringens, CI. septicum) are readily killed even by high dilutions of sodium anacardate. The spores of CI. tetani and CI. septicum survive even a prolonged contact (1 hr) with a 1:100 sodium anacardate solution, whereas the spores of CI. perfringens and aerobic bacilli (Bacillus anthracis, B. subtilis) are very sensitive. Molds and yeasts, with few exceptions, are very resistant. Spirochaeta gallinarum is highly sensitive to the action of sodium anacardate. Cardol, the structural formula of which is: HO-

are both isolated, along with anacardic acid, from Anacardium occidentale. Both are effec-

tive in vitro in preventing the growth of Staph, hemolyticus aureus. In vitro experiments showed a high vermicidal activity of sodium anacardate. Rhabditis fuelleborn (nematodes) died within 30 min in a 1:100,000 solution; cestoids (from the rat intestine), in a 1:4,000 solution after 15 min; ascarids (from the swine intestine), only in a 1:100 solution after 15 min, surviving in a 1:5,000 solution for more than 2Vi hr. Protozoa from a hay infusion showed a varying degree of sensitiveness to sodium anacardate. Ciliates died within 10-12 min in a 1:30,000 solution. Ameboid forms became immobile after 10 min in a 1:5,000 solution. Some flagellates became immobile in a 1:3,000 solution after 20 min; others survived in the same solution for more than IVi hr. Larvae of culicidae were killed within 2 hr. by a 1:20,000 solution of sodium anacardate. TOXICITY.—Sodium anacardate and the related compounds (cardol and anacardol) do not produce any systemic lesion when given by the oral route. Intravenous injs in concentrations of 1:100 and greater produce anaphylactoid shock in guinea pigs and pigeons. Subcutaneous injs of a 1% oily solution are well tolerated; other solutions of this strength cause sterile necrosis. Ointments (2-5%) produce transitory loss of hair in rabbits, but this local effect has not been observed in human subjects. Sodium anacardate has a strong hemolytic activity, which is considerably reduced in the presence of serum. Leukocytes are less sensitive to the cytolyzing activity of the compound. Intravenous inj of 1-2 cc of a 1% sodium anacardate solution is fatal to guinea pigs in a few seconds, the animals dying with the symptoms of anaphylactoid shock. Slow inj of 5-10 cc of a 1% solution into the ear vein oi rabbits causes unrest, dyspnea, and lassitude in some of the animals, but these symptoms disappear after about 30 min. Only when the injs occured rapidly did the rabbits die in shock with opisthotonos and clonic convulsions. These injs caused thrombosis of the ear vein and sometimes sterile necrosis of the surrounding tissue in a number of instances. Pigeons tolerated i.v. inj of 1 cc of a 1% solution without special symptoms, whereas higher concentrations (2.5-5%) killed the animals after 3-5 min, with symptoms not unlike those provoked by neurotoxic snake venoms; i.e., opisthotonos and clonic convulsions. The instillation of a 1% sodium anacardate solution into the conjunctival sack of rabbits did not reveal any irritating action during an observation time of 24 hr. The instillation of a 0.2-1% solution of the compound into the male urethra caused a burning sensation of varying intensity in various individuals tested. EXPERIMENTAL CLINICAL RESULTS IN ANIMALS.—Anthelmintic effects in vivo could be observed in rats, guinea pigs, and rabbits which received the sodium anacardate orally. Rabbits heavily infested with scabies were cured by local application of a 5% ointment of either raw cashew-nut oil or sodium anacardate. Transitory loss of hair occurred in the treated parts. EXPERIMENTAL CLINICAL RESULTS IN HUMAN BEINGS.—Intraurethral instillations of a 0.2% solution of sodium anacardate are generally well supported. Preliminary ex-

It is found in the free state in milk (both fresh and dried) and in the mycelia of Penicillium notatum and Streptomyces griseus and is liberated f r o m gelatin and casein on hydrolysis. The activity of antibacillin is not due to the presence of sulphur or the sulphydryl groups, nor does the substance combine with or destroy bacillin. It probably acts by competing with bacillin for vital systems in susceptible microorganisms. See Woodruff and Foster, 1946a. antibiotic 136, an antibiotic substance produced by a strain of Streptomyces lavendulae. It is extracted from the clarified culture filtrate by adsorbing on Folin Dec also at p H 7.S, eluting with ammonium chloride solution, reabsorbing on Darco G-60, and eluting with hydrochloric acid in aqueous methanol. The eluate is concentrated in vacuo and filtered, and the active material is precipitated with acetone and dried in vacuo. The preparation contains both acid and basic groups and loses about 10% of its activity on boiling at pH 2.0 for 1 hr.

See Bohonos et al., 1947. antibiotic 3510, a grisein-like antibiotic produced by a strain of Streptomyces griseus. Isolation of this agent is accomplished by a method similar to that used for the extraction of grisein. Antibiotic 3510 is not affected by cysteine, glucose, or horse serum. Although iron in the medium of the producing organism favors the production of the active substance, the presence of iron in the test medium reduces the in vitro activity of the agent. There is evidence that this strain of S. griseus may also produce an antimycobacteria factor. SPECTRUM — Antibiotic 3510 inhibits both streptomycin- and grisein-resistant strains of Escherichia coli. In addition, it inhibits Bodenheimer's organism, which is not affected by streptomycin or grisein. It is also effective, to the extent indicated, against the following organisms.

See Garson and Waksman, 1948. antibiotic Els, an antibiotic substance produced by Streptomyces Els. The purified compound is obtained as a fine white precipitate. It resembles actinorubin in its spectrum, general properties, and toxicity. Antibiotic Els is assayed in terms of dilution units, with Escherichia coli communior as the test organism. The producing organism is effective in vitro against the following microorganisms: Achromobacter sp. Aerobacter aerogenes Bacillus sp. Bacillus cereus Bacillus megatherium Bacillus mycoides Bacillus subtilis Corynebacterium xerosis Escherichia coli communior Micrococcus aureus Sarcina lutea Serratia marcescens The active principle inhibits Mycobacterium tuberculosis and Mycobacterium phlei in dilutions of 1:100,000 and 1:500,000, respectively. It is also effective against B. subtilis, E. coli, and Micrococcus aureus. Intraperitoneal inj of 150,000 to 270,000 units/kg in 20-35 gm mice results in death of 1/10 in 5 days.

Extraction of neutral culture filtrates with chloroform yields an active brownish-yellow gum which may be dried to a powder in vacuo. TTie powder is soluble in most organic solvents, stable to heat and acid, but unstable to alkali. The unit of activity is measured in terms of inhibition of Staphylococcus aureus phage. A preparation containing 270 units/mg inhibits Streptococcus fecalis at 300 micrograms/ cc, Bacillus subtilis at 100 micrograms/cc and Staph, aureus at 30 micrograms/cc. Concentrations of 300 micrograms/cc are without effect on Escherichia coli, Salmonella schottmuelleri, Klebsiella pneumoniae. Brucella bronchisepticus, and Mycobacterium tuberculosis hominis. Concentrations of less than 100 micrograms/cc are ineffective against the fungal pathogens of man. The s.c. LD50 is about 9.6 mg/mouse. Seven s.c. doses of 3 mg each over a period of 3.5 days hasten death in mice infected with polio-

One substance is extracted from the ground leaves with water; the filtrate is adjusted to pH 3, boiled, centrifuged, extracted with ether, passed through an alumina column, and crystallized by refrigeration. It is a neutral compound, crystallizing in small, optically active, orthorhombic plates which are soluble in ethanol, acetone, ethyl acetate, and chloroform; sparingly soluble in water and ethyl ether; and insoluble in petroleum ether. The mol. wt. is 336, and the probable formula, Cm H24 On. Staphylococci are inhibited in vitro by 0.5 mg/cc; 2 m g / c c are ineffective against Escherichia coli [1]. This compound is probably an isomer of the one derived from A. minus [2] described below. The second antibiotic principle is obtained as large, optically active prisms, which decompose on slow heating and have the probable formula (C.i H< 0 ) x . They are soluble in methanol, ethanol, chloroform, ethyl acetate, dioxane, and acetone; slightly to moderately soluble in ether, benzene, and water; and insoluble in Skellysolves. The antibacterial activity of this compound is destroyed by cysteine and N-acetylcysteine, but not by S-methylcysteine. SPECTRUM.—Streptococcus viridans is inhibited in vitro by 1 mg/cc. The following are inhibited by 0.7 mg/cc or less: Bacillus subtilis Clostridium botulinum Clostridium oedematiens Clostridium perfringens Clostridium septicum Clostridium tetani Pneumococci Staphylococcus albus Staphylococcus aureus Streptococcus hemolyticus The following are not inhibited by 1 m g / c c : Escherichia coli Proteus morgani Proteus vulgaris Salmonella enteritidis Salmonella paratyphi Salmonella schottmuelleri Salmonella typhi Salmonella typhimurium Shigella flexneri Shigella sonnei TOXICITY.—The parenteral LD50 in mice is about 90 mg/kg. Daily oral doses of 100 mg/kg in mice for 8 days are without ill effect; 500 mg/kg causes loss of weight but no deaths.

It is extracted from the medium by adjusting to pH 4, adsorbing on charcoal, eluting with ether, evaporating, extracting with sodium bicarbonate, precipitating and reprecipitating with acid, and recrystallizing from alcohol [11. A crude product is also reported to have been isolated by extraction at pH 4 with butyl acetate, followed by shaking with sodium bicarbonate and adsorption of impurities on charcoal. The m.p. of the pure acid is 93°C. [3]. The pale cream-colored crystals are soluble in sodium bicarbonate solution, alcohol, ether, acetone, glacial acetic acid, benzene, chloroform, carbon tetrachloride, and pyridine, and are insoluble in water and petroleum ether [1]. It is optically active and remarkably resistant to heat, acid, and alkali [3], The proposed structural formula [4, 10] is as follows:

See Osborn, 1943. circulin, an antibiotic substance which is more effective against gram-negative than against gram-positive organisms [ 1 ]. It is produced by a bacterium closely resembling Bacillus circulans [2]. A substance isolated from a bacterium similar to B. krzemieniewski was originally designated as circulin [3]; it is now known as polypeptin [2]. Circulin is a cyclic compound having the formula (C:WH7o of the same preparation is 23 m g / k g ; the i.v. LDr.o of a preparation containing 2,700 units/mg is 20 m g / k g [5]. Guinea pigs given 18 daily injs of 10 m g / k g of the less pure preparation show only gross loss of weight: there are no morphological changes ascribable to the antibiotic agent. Eighty percent of mice survive 14 daily s.c. injs of 33 m g / k g of pure circulin, but only 10% survive 80 m g / k g . Rats given 200 m g / k g per day orally f o r 7 days exhibit no toxic symptoms [5]. Chronic s.c. administration in mice results in sloughing of tissue at the inj site. Necrotic changes are noted in the kidneys of mice given single large s.c. doses. Chronic parenteral administration causes morphological changes in the kidney, stomach, and skeletal muscles [5]. Heart and respiration rates of anesthetized cats and dogs are unaffected by i.v. inj of 1-3 m g / k g of the pure preparation; the blood pressure is lowered to the extent of 10-20 mm. Hg for 10-30 min [5], ABSORPTION AND EXCRETION .—In dogs, peak blood concentrations of about 55

CISTUS LAURIFOLIUS units/cc and 35 units/cc are reached 1 hr after respective i.v. and i.m. administration of 5 mg kg. Single oral doses of 40 m g / k g result in blood levels of about 60 units/cc in 1-2 hr. After parenteral administration only 10% of the activity is recovered in the urine in 48 hr. Only 6% of the activity is recovered in the urine during the 80 hr following oral administration [5], N o detectable amounts are present in the blood of rats following oral administration of as much as 200 m g / k g [5]. EXPERIMENTAL CLINICAL RESULTS. — I n preliminary prophylactic trials in mice, CI. septicum spores diluted in 2.5% C a C h solution were introduced under the skin of the back and treatment was given at the same site immediately afterward and at 5 and 23 hr. Attempts are being made to establish infections with CI. welchii, CI. novyi, and CI. tetani in order to extend the comparisons [6].

SPECTRUM.—The following microorganisms are inhibited in vitro by citrinin: Minimum inhibitory concentration Organism (mg/cc) 0.1 [10] Bacillus graveolens 0.008 [4], 0.032 [11], Bacillus mycoides 0.05-0.1 [10] Bacillus subtilis 0.016 [11] Escherichia coli 4.0(10] Mycobacterium phlei 0-125 £11] Mycobacterium smegma 0.25 [11] Photobacterium fischeri 0.016 [ 11 ] Pneumococcus 0.05 [10J Pseudomonas aeruginosa more than 15.0 [ 10 Salmonella paratyphi 8.0 [10 Salmonella typhi 1.0(10 Shigella flexneri 2.0-4.0 [ 10 Staphylococcus albus 0.008 [4] Staphylococcus aureus 0.016 [4,11], 0.4 [10] Streptococcus viridans 0.05 [10] Vibrio cholerae 1.0 [ 10] In addition, bacteria may become "sensitized" to citrinin. After 10 treatments with progressively smaller quantities of the antibiotic, the sensitivity of Staph, aureus is increased f r o m 0.4 m g / c c to 0.05 m g / c c . Other organisms that behave similarly are: Bacillus mycoides, E. coli, Ps. aeruginosa, Salm. typhi, Salm. paratyphi, Shig. dysenteriae, and Strep, viridans. Furthermore, treated staphylococci become more susceptible to the action of sulfadiazine [10], PHARMACOLOGY AND TOXICOLOGY. —The LD-.o for rats s.c. or i.v. is 67 mg/kg; for mice i.p. or s.c., 35 mg/kg; for guinea pigs s.c., 37 m g / k g ; and for rabbits i.v., 19 m g / k g [12]. In chronic toxicity tests rabbits survive 10 m g / k g i.v. daily for 26 days followed by 20 m g / k g daily for 26 days [13]. Rats receiving citrinin exhibit intense hyperemia of the ears and feet; this reaction develops within 30 min of administration of the agent and lasts for about 2 hr [12]. Animals given lethal doses show evidence of kidney damage, and those receiving the largest quantities have occasional small foci of myocarditis [12], Other reactions reported are hemorrhages in lungs and liver and accumulation of blood in the chest cavity at autopsy [10]. Repeated i.v. administration in rabbits reduces the amount of hemoglobin but has little or no effect on the number of erythrocytes and leucocytes. Also noted after i.v. inj in rabbits are miosis, hyperemia, salivation, increased bronchial secretion, and lacrimation, none of which is completely eradicated by atropine [12]. Lowering of body temperature is also reported [10]. Local application of 1-5% ointments or 1-20% aqueous solutions causes no irritation to skin of rabbits or humans; a 2 % solution injected i n t r a d e r m a l s has no effect in human beings but causes slight redness in rabbits. Concentrations of 0.8-2.0% are irritating to the mucous membranes of both human beings and rabbits [14], In dogs citrinin has been f o u n d to produce a temporary fall in b.p., dilatation of the blood vessels of the skin and kidneys, and increased peristalsis of the stomach and intestines [ 12]. Another investigator finds that i.v. inj of 60 m g / k g in cats and dogs results in a fall in b p. and slowing of the heart, while very slow inj

[77] of 100 mg'kg has little or no effect. Nasal instillation is without effect on b p. Administration by practically all routes results in demonstrable quantities of citrinin in the blood (14). On isolated organs, citrinin causes bronchial constriction, increased tone of cardiac muscle, frog gastrocnemius, and intestines, and decreased uterine tone. The various pharmacological effects of this agent are characterized by tachyphylaxis [12]. EXPERIMENTAL CLINICAL RESULTS. —Local application of citrinin as a powder is superior to sulfadiazine in the treatment of rabbits infected with Staph, aureus [10]. Mice weighing 18-20 gm are not cured of Siaph. aureus infections by 0.5 mg injs every 5 hr for 3 days [14]. Dramatic results have been obtained in three human cases of staphylococcal and streptococcal infections treated locally with citrinin [10].

TOXICITY AX D PHARMACOLOGY.— T h e i.p. M T D of a crude preparation is 3.5 m g / k g f o r mice [18]. Death results within a few hours a f t e r i.v. inj of 0.5 mg in 20 gm mice; 2.5 mg p.o. and 2 mg s.c. also are lethal [4], Eighty-five percent mortality within three days after i.v. administration of 1.0 mg in 29 gm mice and 100% mortality after 1.5 mg are also reported [10], I.v. inj of 7.5 mg in cats causes a sharp rise in b p., followed by a fall considerably below the initial level [4]. CLINICAL RESULTS.—Solutions of 1:5,000 —1:20,000 applied locally to the nasal passages and the nasopharynx, although tolerated without ill effect, are largely unsuccessful in the treatment of the common cold [10].

colicine, an antibiotic derived from a strain of Escherichia coli isolated from cat feces. It is most active against other strains of E. coli; its inhibitory action on other microorganisms may be due to the production of hydrogen peroxide. Vigorous aeration of the medium is necessary for the production of colicine. Crude colicine is obtained from the medium by adsorption on charcoal, elution with water, boiling in 80% ethanol, drying, taking up the residue in glacial acetic acid, concentrating by vacuum distillation, and precipitating with absolute ethanol. The yield is a dirty-white, nonhygroscopic, chalky solid which is purified by dissolving in water at pH 8.0-8.5, precipitating with phenol, redissolving, and drying. The yield is a brittle, transparent, brown glaze which is nonhygroscopic. Colicine is soluble in water at any p H and in acetic acid, pyridine, and aqueous phenol. It dialyzes through cellophane. It is stable to boiling at pH 2 or 7 for 30 min but is 75% inactivated by boiling at pH 9 for 30 min and 100% inactivated by boiling for 25 min with N / 2 hydrochloric acid or N / 1 0 sodium hydroxide. Colicine is destroyed by pepsin, trypsin, slices of mouse kidney or liver, and the supernatant from centrifuged staphylococcal pus. Small amounts of serum enhance its action. SPECTRUM.—Shigella shigae and Shig. sonnei are approximately as sensitive as the test strain of E. coli. Salmonella enteriditis is 60 times and Salm. paratyphi is 100 times as resistant as the test strain. The following are at least 1,000 times as resistant to colicine as the test strain of Escherichia coli: Escherichia coli, other strains Corynebacterium xerosis El Tor vibrio Mycobacterium phlei Pseudomonas aeruginosa Salmonella newport Salmonella typhi Salmonella typhimurium Shigella flexneri TOXICITY.—Single i.v. injs of 18 mg in 19-20 gm mice produce only transient sickness. Colicine has no effect on human leucocytes at 1:1,000 nor on isolated guinea-pig uterus at 1:5,000. A 1:100 solution of colicine in saline will not lyse human erythrocytes in 20 hr.

See Heatley and Florey, 1946. colicines, a group of antibiotic substances produced by various strains of Escherichia coli [1], Some colicines resist heating to 100°C.; others are completely or partially destroyed after one-half hr at 70°C. [2], Colicines inhibit some strains of E. coli [1]. Some colicines also inhibit Shigella dysenieriae, Shig. sonnei, and some Salmonellae [1]. Most colicines are inactivated by Bacillus meseruericus, B. subtiHs, and Proteus vulgaris [2].

colistatin, an antibiotic produced by an aerobic sporulating bacillus. It is extracted from the culture filtrate by acidification, adsorption on charcoal, and precipitation with acetone. Boiling for 15 min does not affect the activity of the culture filtrate. "The unit of colistatin may be defined as that amount of the substance which is just sufficient to inhibit completely the growth of staphylococci (S. aureus) in 1 ml of nutritive broth for 20 hr at 28 °C." Colistatin is bacteriostatic rather than bactericidal. SPECTRUM.—Colistatin inhibits the following in vitro: Escherichia coli Pneumococci Proteus vulgaris Salmonella schottmuelleri Salmonella typhi Shigella dysenteriae Staphylococcus aureus TOXICITY.—Mice tolerate 100,000 units/kg s.c., i.m., or i.v.

See Mathieson, 1946. crepin, an antibiotic extracted from various parts of the higher plant Crepis taraxacifolia. The active principle occurs as a precursor which is presumably activated by an enzyme occurring principally in the yellow petals and, to a smaller extent, in the roots. A steam extract with no activity acquires full potency after incubation with a raw extract. It is crystallized from ethanol in a variety of crystals which are soluble in pyridine, water, ethanol, ether, and glycerine. The m.p. is above ?00°C. The empirical formula CuHic.Oi is suggested. The activity is destroyed by alkali but is stable to heat and acid. Peptone has no effect on this substance; human serum inhibits its activity. SPECTRUM.—Crepin is effective in vitro a g a i n s t Bacillus subtilis, Salmonella typhi. Staphylococcus aureus, and Streptococcus pyogenes, and is without effect on Pseudomonas aeruginosa.

Dichroa febrifuga, a higher plant (known in China as "Ch'ang Shan"), crystalline derivatives of various parts of which are effective in the treatment of malaria [1, 2]. Two active crystalline alkaloids, designated as alkaloids I and II, are obtained from the roots by boiling the latter with methanol, evaporating, adjusting to pH 8, and extracting with chloroform and hydrochloric acid. The two compounds are then separated by chromatography. Alkaloid I melts at 131°-132°C. and has the probable formula C1GH10N3O3; alkaloid II melts at 140°-142°C. and has the same probable empirical formula as alkaloid I. Both are optically active. In the treatment of malarial chicks, 5 mg/kg of alkaloid I or 2.5 mg/kg of alkaloid II is equivalent to 40 mg/kg of quinine, while 10 mg and 5 mg/kg, respectively, are toxic [2]. Another extract of the root of this plant is reported to be equal to quinine in controlling fever in human tertian malaria but somewhat slower in its antiparasitic effect. In clinical trials, nausea and vomiting are the only symptoms of toxicity. Extracts of the roots and leaves are effective in controlling Plasmodium gaUinaceum infections in chicks but do not prevent relapses [1]. The LD-.o in dogs is 20 gm 'kg; in ducklings, 22 gm/kg; and in chicks, 14 gm/kg [1], Of four crystalline substances which have been isolated from these extracts, only one,

The acid is very soluble in ethanol, slightly soluble in chloroform or water, insoluble in benzene or hexane, and very soluble in aqueous sodium carbonate. It is stable to acid and to alkali at 100° C. and is phenolic in character. The empirical formula is C5H5O3. TOXICITY. — Forty-five mg of the sodium salt given i.p. is tolerated by a 20 gm mouse; 24 mg i.v. and 30 mg orally produce no symptoms. Some of the drug is excreted in the urine but most is destroyed or otherwise disappears in the body. There is evidence of damage to the kidneys. It is reported to be without effect on leucocytes at 1:2,000; at 1:5,000 some leucocytes are still alive after 31/2 hr. See Spray and Robertson, 1947, unpublished; Pollock, 1947, unpublished.

Fumaria officinalis, a higher plant, various extracts of which are ineffective in vitro against Staphylococcus aureus and Escherichia coli [1] and in vivo against experimental malaria [2]. See [1] Osborn, 1943; [2] Spencer et al., 1947. fumigacin, a crystalline antibiotic isolated from culture filtrates of the molds Aspergillus fumigatus [1] and A. fumigatus mut. helvola [2]. It is also known as helvolic acid [2], It is extracted by treating the filtrate with charcoal, adjusting to pH 4, eluting with acetone, distilling, and dissolving in chloroform. Purification is a c c o m p l i s h e d by chromatographic absorption and recrystallization from aqueous acetone [2]. Another method reported [3] is extraction by adsorption on norit, elution with chloroform, and treatment with ether, followed by recrystallization from hot alcohol; this product, however, is probably contaminated with gliotoxin, another antibiotic produced by A. fumigatus [4]. The fine white needles [1, 2, 3] have a m.p. variously reported to be 185°187° [3], 212° [2], and 215°-220° C. [5], The proposed empirical formula is C.isHnOs. Fumigacin is levorotatory. It is sparingly soluble in water, moderately soluble in ether and benzene, and readily soluble in acetone, warm alcohol, chloroform, glacial acetic acid, and pyridine. The sodium salt is fairly soluble in water, but the calcium, magnesium, barium.

[125] iron, copper, zinc, and mercury salts are very sparingly soluble in water. The activity of fumigacin is unaffected by boiling for 15 min at p H 10 or in 2 N acid; it is destroyed by boiling in N alkali for 15 min and by incubating with N alkali at 37° C. for 5 hr. The copper and zinc salts are unaffected by incubation with solutions of copper and zinc sulphate. The activity of the sodium salt is only slightly affected, if at all, by serum, pus, yeast extract, bacterial extract, liver extract, paraaminobenzoic acid, or whole blood [2], SPECTRUM.—Shigella flexneri, Shig. shigae, and Shig. sonnei are not affected in vitro by the sodium salt. The following microorganisms are inhibited [2]: Bacillus anthracis Clostridium oedematiens Clostridium septicum Clostridium welchii Corynebacterium diphtheriae gravis Escherichia coli Mycobacterium smegma Neisseria meningitidis Proteus Pseudomonas aeruginosa Salmonella enteritidis Salmonella typhi Staphylococcus aureus Streptococcus pneumoniae Streptococcus pyogenes Streptococcus viridans The following microorganisms are inhibited by fumigacin: Inhibitory concentration Organism inmg/cc Bacillus anthracis .006 [4] Bacillus mycoides .004 [6] Bacillus subtilis .016 [6], .156 [4] Escherichia coli more than 1.0 [6] Klebsiella pneumoniae .004 [6] Micrococcus tetragenus .06 [4] Mycobacterium phlei more than .032 [6] Mycobacterium smegma more than .032 [6] Staphylococcus albus .004-.006 [4] Staphylococcus aureus .001 [5], .014-.015 [4] Staphylococcus citreus .004 [4] Streptococcus sp. .156 [4] Streptococcus hemolyticus .005-.025 [4] Streptococcus viridans .312 [4] Investigators who used the preparation probably contaminated with gliotoxin reported inhibition of Aerobacter aerogenes, E. coli, Salm, breslau, and Salm. schottmuelleri at l:less than 40,000; B. cereus, B. megatherium, B. mycoides, B. subtilis, and Staph, aureus, at 1:500,000-1:1,250,000; and Sarcina lutea, at 1:4,000,000 [3], The following results have been obtained in tests against various saprophytic and pathogenic fungi [7]: Fungus Units of activity/gm Aspergillus clavatus 3,000 Candida albicans 8,900 Cryptococcus neoformans 30,000 Dematium sp. 22.000 Fusarium sp. 22,000 Pencillium luteum-purpurogenum 8,900 Trichophyton mentagrophytes 8,900, 14,800 A 1:5,500 dilution of fumigacin fails to inhibit the following pathogenic fungi in vitro [8]:

TOXICITY AND PHARMACOLOGY.— Intravenous or s.c. inj of 10 mg of the sodium salt into 20 gm mice results in death within an hr; 5 mg causes toxic symptoms, but the experimental animals recover [2]. By stomach tube, 20 mg doses have no effect on mice [2], The i.p. LDso of fumigacin for 20 gm mice is 400 mg/kg [4] and the maximum tolerated dosage is 800 m g / k g [5]. In chronic experiments, there is 50% mortality in 20 gm mice receiving seven 10 mg doses of the sodium salt over a period of 4 days. Mice receiving ten 2 mg doses p.o. in 5 days show (at autopsy) slight kidney damage and severe liver damage. Six daily i.p. injs of 4 mg each cause 66% mortality, with aseptic plastic peritonitis and necrosis of the liver [2], In rabbits, inj of 0.5 cc of a 1:1,000 solution of the sodium salt into the cisternal space causes no damage or irritation. After 18 hr activity can be detected in the cerebrospinal fluid. Similar inj of a 1:250 solution results in muscular spasm, weakness, fits, and ultimate recovery. Single intradermal injs. cause hyperemia and edema; repeated injs produce fibroblastic reactions but no necrosis [2], A 1% solution of the sodium salt kills leucocytes within an hour; 1:1,600 is without effect. The sodium salt is excreted in bile and urine after administration by a n y r o u t e in mice [2], EXPERIMENTAL CLINICAL RESULTS — Doses of 1-10 mg given one to ten times at 12 hr intervals, i.v., s.c., and p.o., fail to protect mice from infections due to Staph, aureus and Strep, pyogenes but do prolong life. The very few mice that survive the infection die later, probably as a result of liver damage [2]. In Strep, hemolyticus infections in mice one or two s.c. injs of 2-4 mg give 50% protection [4].

Fusarium bostrycoldes, a fungus, the culture fluid of which strongly inhibits the growth of the tubercle bacillus, H-37, when tested in vitro. The inhibiting action was found to be related to pigment production by the mold. The pigments were extracted from the mold mycellium with hot alcohol and from the highly colored culture fluid with benzene. After freeing of the extracts from fat by adsorption on alumina, a crystalline pigment was obtained with antibiotic activity toward the tubercle bacillus similar to the activity of streptomycin. This pigment, which has indicator properties, melts at 238°-239°C. and is a naphthaquinone similar to, but not identical with JAVANICIN. See Cajori et al., 1950.

Pénicillium expansum, Pythium ultimum, Rhizoctonia crocorum, Rh. solani, Verticillium dahliae [12]. Filtrates from A. fumigatus presumably containing gliotoxin as the active principle fail to inhibit Treponema pallidum, Plasmodium lophurae, Trypanosoma lewisi, staphylococci, streptococci, pneumococci, meningococci, and Escherichia coli [11]. Filtrates from Gliocladium fimbriatum inhibit the spores of Sclerotinia americana and the hyphae of Rh. solani [2].

TOXICITY.—In rabbits i.v. inj of 45 mg/kg causes death in 1 hr, preceded by diarrhea and low blood pressure. The lethal i.p. and p.o. dose is 50 mg/kg for mice and 50-65 mg/kg for rats. In mice 25 mg/kg by either route results in only 50% mortality [6], Culture filtrates from A. fumigatus, apparently containing gliotoxin as the active agent, nave no effect on human sperm, rabbit tracheal cilia, or sheep erythrocytes. Although effective in vivo at 1:10-1:80 against cells of experimental lymphosarcoma, sarcoma, and carcinoma, these filtrates have no beneficial effect, even in nearly fatal doses, on the development of tumors in vivo in mice [11].

See Osborn, 1943. glutinosin, a crystalline fungistatic substance extracted from the culture filtrates of the mold Metarrhizium glutinosum. After extraction with ether, normal butanol, or petroleum ether, the supernatant is evaporated and the thin, colorless, plate-like crystals of glutinosin are recrystallized from ethanol. The m.p. is above 300°C. The empirical formula appears to be CisHeoOis.

Glutinosin is ineffective in vitro at 100 micrograms/cc against Escherichia coli. Salmonella typhi, and Staphylococcus aureus. Concentrations at or below 50 micrograms/cc at pH 3.5 prevent the germination of spores of Botrytis allii, Fusarium coeruleum, and Penicillium expansum, but not F. graminearum. An a s s o c i a t e d substance, with irritating properties similar to those of poison ivy, is extracted from the culture filtrates with glutinosin but remains in the mother liquor after the crystallization of glutinosin.

It may be separated lrom tyrocidine, the other component, by virtue of the fact that it is soluble in an alcohol-ether mixture, while tyrocidine is not [1]. Separation of the two components is also effected by extracting tyrothricin with warm absolute acetone to dissolve the gramicidin [2]. It is purified by precipitating f r o m the acetone solution with ether, evaporating, and recrystallizing from warm absolute acetone [2]. The crystals appear as tiny platelets with pointed or rectangular ends, which have a m.p. of 228°-231"C. They are soluble in lower alcohols, acetic acid, acetone, and dioxane, and almost insoluble in water, ether, hydrocarbons, and chlorinated hydrocarbons [3]. The mol. wt. is 1,054 or 1,413 [4], A large proportion of the a-amino acids in the molecule have the d-configuration. It contains 1-tryptophane, d-leucine, and alanine [5]. It is hydrolyzed by acid; but it is completely resistant to the action of pepsin, trypsin, and papain [5] and is only slightly inhibited by serum, tissue extracts, and peptone [4], Gramicidin is principally bacteriostatic in action, but large c o n c e n t r a t i o n s are bactericidal [2], Gramicidin, while less hemolytic than tyrocidine, exhibits a "definite hemolytic effect" [6], 0.05 ppm being required to cause 50c£ hemolysis of rat erythrocytes in 40 min at rm. temp. [7]. It also depresses the surface tension of aqueous solutions [8]. Heat destroys the antibacterial and hemolytic activity of the agent but does not affect its property of lowering surface tension [8], Mixtures of gramicidin and penicillin exhibit a synergistic effect [9]. SPECTRUM.—The following organisms are inhibited in vitro by gramicidin: Bacillus anthracis [2] Clostridium spp. [2] Corynebacterium diphtheriae [10] Diphtheroid bacilli [10]

GRAMICIDIN S Diplococcus pneumoniae [2] Endameba histolytica [11] Gaffkya tetragena [2] Gonococci [10] Lactobacillus acidophilus [2] Meningococci [10] Mycobacterium leprae [2] Mycobacterium phlei [2] Mycobacterium ranae [2] Mycobacterium tuberculosis [2] Staphylococcus aureus [2] Staphylococcus citreus [2] Streptococcus fecalis [2] Streptococcus hemolyticus [2] Streptococcus mastitidis [2] The following are not affected by gramicidin:

Ascaris suis [11] Bartonella bacilliformis [12] Escherichia coli [10] Leishmania tropica [12] Leptospira icterohemorrhagiae [12] Trypanosoma cruzi [12] Trypanosoma lewisi [12] TOXICITY.—Mice are killed by single i.p. injs of 0.3-0.6 mg [1,2, 10], The i.p. M T D i s l O m g / k g [13]. Single i.v. injs of 0.075 mg are fatal to 20 gm mice [2], The i.v. M T D is 1.2 m g / k g [13], and the i.v. LD50 is 1.5 m g / k g [11]. Large oral and s.c. doses are tolerated, the M T D for both routes being more than 1,000 m g / k g [13], In 150-200 gm rats 20 m g / k g i.p. is lethal [7], and in dogs, 3 m g / k g i.v. is fatal in 48-72 hr [10], EXPERIMENTAL CLINICAL RESULTS. —Intraperitoneal inj of 0.001-0.002 mg protects mice against 10,000 lethal doses of pneumococci or Strep, hemolyticus; i.v., s.c., and i.m. injs are ineffective [10]. In pneumococcal hypopyon ulcers in rabbits, only slight beneficial effects are noted after local treatment of the lesions with gramicidin [14], VETERINARY CLINICAL RESULTS.— Bovine mastitis responds to gramicidin treatment when the causative organism is Strep, agalactiae [15]. Of four cases due to Strep, uberis, the results were satisfactory in only one [15], CHEMICAL DERIVATIVES OF GRAMICIDIN.—A formaldehyde derivative of gramicidin having the same antibacterial activity as the free substance is considerably less toxic and less hemolytic than gramicidin [7], Tlie lethal dose of the formaldehyde product for 150-200 gm rats is more than 450 m g / k g , while 0.6 ppm is required to produce 50% hemolysis in rat erythrocytes in 40 min at rm. temp. [7], The i.v. LDoo for mice is 4.7 m g / k g [11], Other derivatives have an i.v. LD30 for mice as high as 30 m g / k g [16].

talline polypeptide compound [2] which is extracted from the culture filtrate by acidifying to p H 4.7, drying, taking up the residue in alcohol, and passing through a Seitz filter. Purification is effected by diluting the alcohol extract with water, removing lipoids with ether, adsorbing other impurities on charcoal, and refrigerating for crystallization [3]. The m.p. is 267-270°C. [1, 3J. The antibiotic is soluble in chloroform [1], ethanol, and acetone [2] and insoluble in water, acids, and alkalis [2], The dry crystals are stable at 160°C. Gramicidin S also resists autoclaving for 30 min at 120°C. [3], SPECTRUM.—The following organisms are inhibited by 7-10 micrograms/cc. Staphylococcus aureus, streptococci, Diplococcus pneumoniae, Clostridium histolyticum, and CI. welchii. Vibrio cholerae is inhibited by 25 micrograms/cc [3]. Gramicidin S is also effective against Escherichia coli [1]. TOXICITY.—The i.p. LDso in rats is 17 mg/kg. Human leucocytes are not affected by 400-800 micrograms/cc [3]. EXPERIMENTAL CLINICAL RESULTS. —Gramicidin S is highly effective in the treatment of guinea pigs [3] and rats [1] infected with CI. welchii. CLINICAL RESULTS.—Local application of gramicidin S is of value in the treatment of the following conditions in human beings: Abscesses [1, 4] Bums [1, 4] Empyema [1, 4] Gunshot wounds [1] Impetigo, contagious [4] Osteomyelitis, acute and chronic [1, 4] Otitis [1] Peritonitis [4] See [1] Gause and Brazhnikova, 1944b; [2] Belozersky and Passhina, 1944; [3] Gause and Brazhnikova, 1944a; [4] Sergiev, 1944. gramldlnlc acid, see TYROCIDINE. gramlnlc acid, see TYROCIDINE. gram-negative bacillary subacute bacterial endo-

It is extracted from the culture filtrate by adsorption on norit, elution with 95% ethanol, and precipitation with methanol and acetone. Crude grisein is soluble in water and in 95% ethanol and insoluble in absolute ethanol, ether, and acetone. It is stable to 100°C. for 10 min and is not affected by cysteine, sodium thioglycolate, hydrazine, hydroxylamine, or semicarbazide. Although the presence of iron in the culture medium of the producing strain of S. griseus facilitates the production of grisein, it decreases the action of the antibiotic. Sensitive organisms develop resistance to grisein rapidly but show no evidence of cross resistance to streptomycin and streptothricin. Mixtures of grisein and streptomycin exert a synergistic effect on organisms sensitive to both agents [2]. SPECTRUM.—The following organisms are inhibited in vitro by grisein; Units of activity/mg of a "potent Organism preparation" Aerobacter aerogenes less than 30 Bacillus cereus 1,000 Bacillus megatherium 1,000 Bacillus mycoides less than 30 Bacillus subtilis 300 Escherichia coli 1,800 Klebsiella pneumoniae less than 30 Micrococcus lysodeikticus 30,000 Mycobacterium phlei less than 30 Mycobacterium tuberculosis less than 30 Proteus vulgaris less than 30 Pseudomonas aeruginosa less than 100 Pseudomonas fluorescens less than 100 Salmonella pullorum 30,000 Sarcina lutea less than 30 Serratia marcescens less than 100 Shigella alkalescens 1,800 Shigella dysenteriae 18,000 Shigella paradvsenteriae 18,000 Staphylococcus aureus 3,000

The culture medium inhibits Staph, aureus but not E. coli [2], See [1] Robbins et al., 1945; [2] Wilkins, 1947b. hirsutic acids, a group of one inactive acid precursor, two antibacterial acids, and four unidentified antibacterial substances obtained from the culture medium of the mold Slereum hirsutum. Hirsutic acid C is the inactive crystalline precursor with the formula C15H20O4 which is obtained by amyl acetate extraction of the culture fluid. The large rhombohedral crystals, which have a m.p. of 179.5°C., are optically active, sparingly soluble in water, and soluble in most organic solvents except hexane and carbon tetrachloride. Mice weighing 31 gm survive a single i.v. inj of 24 mg of hirsutic acid C. Noncrystalline hirsutic acid N occurs naturally in the culture fluid and may also be obtained by incubating acid C with the fungal mycelium or a mycelial extract. Extraction with ether and water isolates this acid from the amyl acetate extract of the culture fluid. It is a transparent, colorless, noncrystalline solid, slightly soluble in hot water and soluble in alkali and most organic solvents. The free acid, which has no sharp m.p., is indefinitely stable as the solid or in ether solution; it is less stable as the sodium salt in water solution. Hirsutic acid N inhibits in vitro the following microorganisms: Bacillus anthracis, B. subtilis, Corynebacterium diphtheriae, El Tor vibrio, Micrococcus lysodeikticus, Neisseria meningitidis, Sarcina lutea, Staphylococcus aureus, and Streptococcus pyogenes. It is ineffective against Aerobacter aerogenes, Chromobacterium prodigiosum, Escherichia coli, Klebsiella pneumoniae, Proteus, Pseudomonas aeruginosa, and Salmonella typhi. A crude preparation having one-eighth to one-fourth of the activity of the pure acid kills l e u c o c y t e s i m m e d i a t e l y at 1:4,000; 1:16,000 has no effect. Mice weighing 20-22 gm tolerate single i.v. doses of 1-2 mg; 6 mg doses are fatal within 5 min. Oral doses of 20 mg have no effect. Intravenous administration in cats causes a rise in b.p. but does not change respiration. Perfusion of the cat heart with a 1:25,000 dilution causes irreversible slowing, relaxation of tone, and dimunition of a m p l i t u d e . Acid N causes no specific changes in the motility of the isolated guineapig uterus. Hirsutic acid A, also noncrystalline, is obtained by treating acidified ether extracts of acid C with alkali. It is soluble in the agents that dissolve acid C. It is effective in vitro against Staph, aureus and Strep, pyogenes and ineffective against E. coli and Salm. enteritidis. Acid A is similar to acid C in its effect on leucocytes but is less toxic to 20-22 gm mice, 20 mg i.v. being required to cause death. No changes are observed in b.p and respiration of the cat after

i.v. inj. Perfusion of the rabbit heart with dilutions of 1:10,000 and 1:50,000 results in a slight, reversible decrease in amplitude, rate, and coronary flow. Of the four unidentified antibiotic agents obtainable from this fungus, two occur naturally; one results from the action of dry heat on acid C; and the fourth, from the action of acid on acid C.

Two-week-old chicks injected with the extracts mixed with blood containing Plasmodium gallinaceum fail to develop malaria. In addition, the extracts are somewhat effective in the treatment of experimental malaria in

chicks but are without effect in Diplococcus pneumoniae infections in mice. Doses of 0.5 to 1.0 cc injected i.p., s.c, or i.v. in chicks and mice are lethal. Smaller amounts are anesthetic. See Carlson et al., 1946. hydroxy streptomycin, an antibiotic derived f r o m Streptomyces griseo-carneus exhibits an in vitro antibacterial spectrum similar to that of streptomycin. Its activity per mg when assayed against Bacillus subtilis is equivalent to 784 micrograms of streptomycin base. The empirical formula has been calculated as C21H39 NTOIS. Degradation experiments show the presence of the streptidine and N-methylglucosamine fragments of streptomycin. The streptose portion of the new antibiotic yields, instead of maltol, a crystalline product which is presumably 2-hydroxymethyl 3-hydroxy 1, 4pyrone; i.e., a hydroxylated maltol. The hydroxystreptomycin yields the hexa-acetate of a disaccharide while dihydrostreptomycin gives a penta-acetate.

Aqueous extracts of all parts of fusaria-wiltresistant sweet potatoes and of the tubers and stems of susceptible plants stimulate Fusarium oxysporum f. batatas, F. oxysporum f. lycopersici, Escherichia coli, and Staphylococcus aureus and are without effect on Mycobacterium phlei. Aqueous extracts of wilt-susceptible sweet-potato leaves and roots and water-insoluble residues from all parts except the tubers of resistant plants are slightly inhibitory for F. oxysporum i. batatas. Antibacterial activity is shown by the water-soluble residue resulting from methanol extraction of dried and ground parts of both wilt-susceptible and resistant plants. However, only extracts of the stems of wilt-susceptible plants inhibit Myco, phlei. Various partially purified extracts of the stems of wilt-susceptible plants inhibit the following microorganisms: Bacillus cereus Bacillus subtilis Escherichia coli Fusarium oxysporum f. batatas Fusarium oxysporum f. lycopersici Mycobacterium phlei Rhodococcus roseus Sarcina lutea Serratia marcescens Staphylococcus aureus Xanthomonas translucens f. sp. hordei-avenae This antibacterial action is accompanied in many cases by stimulation of the test organism [1].

KALANCHOE FLAMMEA

The compound is a yellow substance, melting at 155 C. Although it is insoluble in water, it is soluble in aqueous solutions of sodium hydroxide and hot acetic acid; and is very soluble in chloroform. The empirical formula is C10H6O3 and the structural formula is 5-hydroxy-l, 4, naphthoquinone. TOXICITY.—Juglone has been reported as being toxic to fish and to the noncutinized surfaces of root tissues. EXPERIMENTAL CLINICAL RESULTS, HUMAN BEINGS.—Juglone is reported to be effective when applied locally to persistent ringworm (Microsporum audouini, Trichophyton sp., Tinea) infection. The use of the green husks of the black walnut for control of ringworm can be traced back to the Greeks and Romans. Brissemoret and Michaud (1917) recorded the effective clinical use of juglone against eczema, psoriasis, impetigo, and other skin diseases. It has also been shown that the antibiotic is effective in terminating the growth of germinating fungus spores. See Gries, 1943; Brissemoret and Michaud, 1917.

See Hayes, 1947. Juniperus occidentals, a higher plant (the jumper), extracts of which are effective in vitro against Staphylococcus aureus. Twoweek-old chicks injected with the extracts mixed with blood containing Plasmodium gallinaceum fail to develop malaria. However, the extracts are ineffective in the treatment of experimental malaria in chicks and Diplococcus pneumoniae infections in mice. Doses of 0.5 to 1.0 cc. injected i.p., s.c., or i.v. in chicks and mice are lethal. See Carlson et al., 1946.

compound with javanicin having a m.p. of 178°C. Javanicin is ineffective in vitro against Bacterium tumefaciens, Pseudomonas jluorescens, and Ps. aeruginosa and is effective against Bacillus subtilis, Bacl. fascians, Clostridium welchil, Escherichia coli, Mycobacterium phlei, Myco, tuberculosis hominis, Staphylococcus aureus, Streptococcus hemolyticus, and Strep, pyogenes [1, 2]. It is bactericidal for Myco, tuberculosis hominis in c o n c e n t r a t i o n s of 1:50,000-1:100,000 [1]. This action is not affected by the presence of serum [1], but Strep, hemolyticus is not inhibited by javanicin when grown on a blood medium [2]. The maximum tolerated dose in mice i.p. is 10 mg. Local treatment of tuberculous ulcers in guinea pigs shows only minimal therapeutic effects [2]. See [1] Arnstein et al., 1946b; [2] Arnstein et al., 1946a; [3] Arnstein and Cook, 1947.

Lateritiin I, CKHIOOINJ, which has a m.p. of 121°-122°C., is produced by f . lateritium. Lateritiin II, also CIKHIGOTN^., m.p. 125°C., is obtained from F. sp. (probably lateritium). The active principles are colorless, optically active, neutral, sparingly soluble in water, and very soluble in organic solvents. They are stable to mineral acids and to heat and unstable to alkalis. Both are active in vitro against Bacillus subtilis, Mycobacterium phlei, Staphylococcus aureus, and Streptococcus pyogenes. In addition, lateritiin I is effective at 1:160,000 to 1:640,00>0 against Myco. tuberculosis and has low toxicity for mice on i.p. inj. See Cook et al., 1947. laterosporin A and B, two antibiotic substances produced by the bacterium Bacillus laterosporus. The active principles are isolated by adjusting the culture fluid to p H 2, adsorbing on charcoal, eluting with acidified butanol, and extracting with ether and water. T h e water concentrate is adjusted to pH 6.8-7.0 and the activity is precipitated by the addition of picric acid. The picrate is then converted to the hydrochloride by suspending in alcohol containing hydrochloric acid. The acid-alcohol insoluble portion is laterosporin B. It is purified by dissolving in hydrochloric acid containing sodium chloride, extracting with butanol, and precipitating with ether. The product is a cream-colored powder. Laterosporin A, a lightbrown powder, is precipitated from the acidalcohol solution by the addition of ether. Both substances appear to be peptides and both are soluble in water. Laterosporin A is not destroyed by trypsin and is stable to boiling for one half-hour in the pH range 2-8. It dialyzes through a cellophane membrane. The standard is laterosporin A hydrochloride, 1 mg containing 10 units. Horse serum reduces the activity of both substances.

TOXICITY —Oil A diluted 1:100 in mineral oil and injected i.p. in 0.25-0.5 cc amounts in mice causes a staggering gait for a brief period, but the animals survive. Intraperitoneal injs of 0.25 cc of a 1:3 dilution are fatal. See Carlson and Douglas, 1948b. Leptotaenia multifeda, a higher plant, from the root of which an antibiotic substance is extracted. The macerated root is extracted with ethyl acetate, the extract evaporated, and the resulting oil washed with water. Purification is effected by washing the crude oil with sodium bicarbonate solution and water, dissolving in absolute alcohol, and adding an alcoholic solution of sodium bisulphite, followed by filtration, washing the precipitate with alcohol, and adding a mixture of acetic acid and petroleum ether. The ether layer is then washed with water, dried over sodium sulphate, and evaporated under reduced pressure. The resulting oil is dissolved in benzene, passed through a column p a c k e d with Magnesol-Celite, and eluted with a 200:1 benzene-ethanol mixture. Evaporation of the solvent yields a viscous oil the activity of which is somewhat reduced when subjected to 100°C. for 1 hr.

The active substance is ineffective in vitro against Aerobacter aerogenes, Klebsiella pneumoniae, and Salmonella schottmuelleri. It inhibits the following in vitro: Bacillus subtilis Corynebacterium diptheriae Diplococcus pneumoniae Escherichia coli Micrococcus aureus Mycobacterium lacticolor Mycobacterium phlei Mycobacterium tuberculosis hominis Neisseria catarrhalis Proteus vulgaris Pseudomonas aeruginosa Serratia marcescens Streptococcus pyogenes Vibrio comma Mice survive s.c injs of as much as 2.5% of total body wt. of the bisulphite purified preparations without any noticeable change in behavior.

LICHENIFORMIN

II«]

tkhcalfomliK, an antibiotic substance produced by Bacillus licheniformis. It is isolated from the whole culture by repeated adsorption on charcoal and elution with acidified aqueous n-butanol, followed by conversion to the picrate, and finally conversion to the hydrochloride, a solid white material. Licheniformin hydrochloride is stable to autoclaving for 10 min at pH 1-9; however, 75% of its activity is lost on standing at rm. temp, at pH 7 in the light for 6 mo. The dry preparation withstands storage in the light at rm. temp. The hydrochloride is soluble in water, methanol, and ethanol, and insoluble in dry n-butanol, acetone, and nonpolar organic solvents. It does not melt but chars on strong heating. The activity is unaffected by the presence of serum. The size of the inoculum of test organisms has a definite effect on the end point. Mycobacterium phlei is the standard test organism, one unit being the equivalent in potency of 0.2 micrograms of a standard preparation. SPECTRUM.—A preparation of licheniformin assaying 2.5-5 million units per gm inhibits the following organisms in vitro: Inhibitory Organism concentration Actinobacillus lignieresi l:less than 10,000 Bacillus anthracis 1:200,000 Brucella abortus 1:320,000 Corynebacterium 1:1,250,000 — diphtheriae 1:10,000,000 Corynebacterium equi 1:5,000,000 Corynebacterium ovis low activity Corynebacterium pyogenes low activity Corynebacterium renale 1:40,000,000 Diplococcus pneumoniae\: 160,000—1:20,000 Erysipelothrix rhusiopathiae l:less than 5,000 Escherichia coli 1:80,000—1:10,000 Mycobacterium phlei 1:5,000,000— 1:2,500,000 Mycobacterium 1:640,000— tuberculosis 1:160,000 Pasteurella septica 1:640,000— l:less than 5,000 Pseudomonas aeruginosa 1:40,000 Salmonella schottmuelleri 1:20,000—1:10,000 Shigella dysenteriae 1:160,000—1:40,000 Staphylococcus 1: 5,000,000— pyogenes 1:1,250,000 Streptococcus spp. 1:1,250,000— 1:80,000 Streptococcus viridans 1:20,000 Vibrio cholerae 1:20,000 TOXICITY —The LDso for 18-20 gm mice is 5 mg i.v., 7.5 mg i.p., and 10 mg s.c.; the LDo values are 2.5 mg i.v., 2.5 mg i.p., and 5 mg s.c. Eighty-five percent of mice survive s.c. mis of 6 mg per day in two daily doses for 5-6 wks, but survivors are in poor condition and show glomerular-tubular damage in the kidneys. In cats 1-2 mg/kg causes a transient, sharp fall in b.p.; 10-20 mg/kg doses result in a shocklike condition. Licheniformin is not hemolytic, but it delays coagulation of the blood. ABSORPTION.—After s.c. inj in mice, the activity is present in the blood in detectable amounts.

EXPERIMENTAL CLINICAL RESULTS.— Total s.c. doses of 3.5-35 mg over a period of 3 days prolong life but do not prevent death in mice with Staph, pyogenes infections. A total of 18 mg s.c. in 3 days is somewhat more efficacious in Strep, pyogenes infections. In B. anthracis infections 3 s.c. injs of 3 mg each in one day prevent death in 84% of mice [1], The agent is of little value in the treatment of Coryne. diphtheriae infections in mice [2]. It is effective in reducing the severity of lung damage in mice with experimental tuberculosis, but the most effective dosage is also nephrotoxic [1].

See Cardoso and Santos, 1948. litmocidin, an antibiotic pigment produced by Proactinomyces (formerly Actinococcus) cyaneus-antibioticus [1]. The pigment is extracted from the culture medium with water [2], The water extract is acidified, precipitating an inactive protein with the active pigment. The protein and pigment are separated by repeated solution and precipitation, which results in an aqueous solution of the pigment. The active principle is obtained by adsorption from the water extract on charcoal, acidification, elution with acid acetone, and reprecipitation [2], Litmocidin is red when acid, blue when alkaline, and violet when neutral [1,2]. The acid form is soluble in water, ethanol, and acetone, and is stable to boiling in the acid range for 30 min. The m.p. is 144M46°C. (decomp.) [2]. The activity of this substance is unaffected by 10-30% human or horse serum. It is bactericidal as well as bacteriostatic for some microorganisms. "The unit of activity of litmocidin is that quantity of the substance which is just sufficient to inhibit completely the growth of Staph, aureus in one ml. of broth" [1], SPECTRUM.—Litmocidin is very strongly inhibitory for Mycobacterium tuberculosis. It inhibits the following in vitro at dilutions of 1:500,000 to 1:4,000,000 [1]: Staphylococcus aureus Streptococcus hemolyticus Streptococcus viridans Vibrio comma Escherichia coli, Salmonella paratyphi, Saint, schottmuelleri, Salm. typhi, and Shigella dysenteriae are inhibited by 1:1,000 to 1:10,000 [1].

TOXICITY.—Twenty-gram mice survive i.p. injs of 3,000 units; 4,000-5,000 units i.p. causes 50% mortality; 100% are killed by 10,000 units [1]. EXPERIMENTAL CLINICAL RESULTS — Subcutaneous injs of 50-500 units, one to three times a day for 3 days in mice infected with Staph, aureus, have no chemotherapeutic effect [1], See [1] Gause, 1946b; [2] Brazhnikova, 1946.

See Osborn, 1943. lupuion and bumulon, two crystalline antibiotic agents extracted from the strobiles of the hops plant, Humulus lupulus. Lupuion is isolated by extracting the dried and ground hops with petroleum ether, concentrating the extract in vacuo, crystallizing by refrigeration, and recrystallizing from petroleum ether and aqueous methanol. The o-phenylenediamine salt of humulon is obtained by diluting the mother liquor from the lupuion crystals with petroleum ether, heating to 40°C., adding o-phenylenediamine in boiling benzene, crystallizing by refrigeration, and washing the crystals with cold benzene and petroleum ether. The free substance is obtained by converting to the lead salt and treating with sulphuric acid. Both substances are fairly soluble in organic solvents such as methanol, ethanol, petroleum ether, hexane, and iso-octane, and slightly soluble in neutral or acidic water. Lupuion is moderately stable to acid and alkali but is inactivated at rm. temp, when exposed to air [1]. Sodium chloride and serum decrease its activity [2], Humulon is relatively stable to acid. The presence of ascorbic acid protects the bacteriostatic property of both agents [1]. Lupuion has the formula C26H3SO4 and melts at 92°C. It is optically inactive. Humulon, C21H30O5, is optically active and melts at 55°C. [1]. Lupuion may exist in any of the forms indicated by the three following structural formulas; it may be noted that forms B and C probably predominate [3].

See Osborn, 1943. tardin, a noncrystalline antibiotic produced by the fungus Penicillium tardum. It is extracted from the culture filtrate by adjusting to pH 7, shaking with amyl acetate, distilling, dissolving the residue in benzene, and passing this solution through an aluminum oxide column at pH 5. The product is a pale-yellow oil with the proposed formula C11H1DO3. It is stable in the pH range 2-8 and is laevorotatory in alcohol. Tardin is slightly soluble in water and in warm hexane and is soluble in alcohol, acetone, ether, benzene, and amyl acetate. It is inactivated by the presence of serum. SPECTRUM.—Corynebacterium diphtheriae gravis, Coryne. xerosis, Salmonella enteriiidis, Staphylococcus aureus, and Streptococcus viridans are inhibited by tardin, but Pseudomonas aeruginosa and Escherichia coli are not affected by concentrations of 1:1,000. The following pathogenic fungi are inhibited by 1:5,000; Sabouraudites audouini, S. lanosus, Trichophyton equinus, and T. sabouraudii. Trichophyton lacticolor, T. tonsurans, and Endomycopsis albicans are not affected by the same concentration. None of the fungi listed is inhibited at 1:20,000. TOXICITY— Leucocytes are killed in 30 min in a 1:2,000 solution of tardin; 1:16,000 is without effect. In 20 gm mice single injs of 0.8 mg i.v. or 2.5 mg s.c. produce only transient illness; larger doses cannot be tried because of poor solubility. In the isolated guineapig uterus solutions of 1:25,000 cause irreversible increase in contractions, followed by

stoppage of contractions. Intravenous inj of 30 mg causes a transitory fall in b.p. in a 2.5 kg cat. See Borodin, et al., 1947.

The m.p. is 185°C. (decomp.). The crystals occur in several forms depending on the method of crystallization used. The agent is soluble in water, methanol, ethanol, acetone, and propylene glycol and is insoluble in ether and petroleum ether. It is stable for long periods at pH 2-5 in aqueous solution at rm. temp. The hydrochloride and the sodium salt, both crystalline compounds, have been obtained.

LDo in mice for the hydrochloride is equivalent to 103 m g / k g of the amphoteric compound. The i.v. LDso is 192 mg/kg. EXPERIMENTAL CLINICAL RESULTS. —Terramycin is effective both orally and pare n t e r a l ^ in the treatment of mice infected with Diplococcus pneumoniae, Kleb, pneumoniae, Salm. typhi, and Streptococcus hemolyticus. It may also be effective against rickettsiae and the influenza virus in chick embryos [1]. ABSORPTION AND EXCRETION. — Determinations of absorption and excretion of terramycin in human beings indicate that this drug is readily absorbed after oral administration. The maximum serum concentrations attained after oral doses of 50 m g / k g were 12 to 16 micrograms/ml. Reasonably high serum concentrations were maintained with daily doses of 50-100 m g / k g by mouth. Measurable concentrations were obtained in the cerebrospinal fluid and in other body fluids when sufficiently large doses had been administered. High concentrations of drug were attained in the urine. See [1] Finlay et al., 1950; [2] Werner et al., 1950. For literature on spectra, absorption, excretion, toxicity, and laboratory and clinical experimental indications see Hendricks et al., 1950; Hobby et al., 1950a; Hobby et al., 1950b; King et al., 1950; Werner et al., 1950; for some of the reports presented at the Conference on Terramycin (June, 1950), see Herrell et al., 1950; Kneeland, 1950 (atypical pneumonia); Knight, 1950 (brucellosis); P'an, 1950; Rose, 1950 (rickettsiapox); Smadel et al., 1950 (typhus); Welch, 1950; Woodward et al., 1950 (rickettsial and bacterial infect i o n s ) .

terrelc acid, an antibiotic isolated f r o m Aspergillus terreus which is effective in vitro against Staphylococcus aureus, Escherichia coli, Pseudomonas pyocyanea. Streptococcus hemolyticus, and Salmonella typhi. On crystallization it assumes the form of colorless plates. Its m.p. is 120°-121°C. It is very soluble in ether, benzene, ethyl alcohol, and acetone, and is slightly soluble in water and in hexane. It is stable at p H 2 at 37°C., but not on boiling. At p H 10 all activity is lost on incubating at 37 °C. f o r 3 hr. The empirical formula is CTHSO-I. TOXICITY.—Intravenous inj of 2 mg of the sodium salt kills a 20 gm mouse in about 2 hr; 0.75 mg is without effect. Intermediate doses are fatal in several hours. A concentration of 1:2,000 kills human leucocytes at once; at

1:16,000 leucocytes are killed within an hour. Only at 1:250,000 is the effect of terreic acid solution the same as that of the control solution. The vapor causes irritation of the nose and throat.

tyrocidine, a crystalline polypeptide antibiotic, one of two active components of tyrothricin [1]. It is identical with the substance first designated as graminic acid. The crystalline preparation originally known as gramidinic acid is a mixture of free tyrocidine and its hydrochloride [2], Tyrocidine is separated from gramicidin, the other active component, by extracting the gramicidin from tyrothricin with a mixture of ether and acetone [2] or with warm absolute acetone alone [3], The residue is dissolved in boiling absolute alcohol, and crystallization of the hydrochloride is effected by the addition of alcohol containing hydrochloric acid. The product is recrystallized from absolute methanol. Tyrocidine hydrochloride crystals occur as fine colorless needles or rods with a m.jj. of 240°C. (corr., decomp.) [2], The substance contains tryptophane, tyrosine, and aspartic acid. It is resistant to the action of pepsin, trypsin, and papain [4], Human and rabbit erythrocytes are hemolyzed by tyrocidine [5|- The active material depresses the surface tension of aqueous solutions to a greater extent than does gramicidin. It is less affected than gramicidin by the action of serum [6], SPECTRUM.—In general tyrocidine is less active than gramicidin. It is effective in vitro against the following organisms: Bacillus anthracis [3] Clostridium spp. [3] Corynebacterium diphtheriae [7] Diphtheroid bacilli [7] Diplococcus pneumoniae [3] Escherichia coli [7] Gaffkya tetragena [3] Gonococci [8] Hemophilus spp. [7] Klebsiella spp. [7] Lactobacillus acidophilus [3] Leishmania tropica [9] Meningococci [8] Mycobacterium leprae [3] Mycobacterium phlei [3] Mycobacterium ranae [3] Mycobacterium tuberculosis [3] Neisseria spp. [7] Salmonella spp. [7] Shigella spp. [7] Staphylococcus aureus [3, 7] Staphylococcus citreus [3] Streptococcus spp. [7] Streptococcus fecalis [3] Streptococcus hemolvticus [3] Streptococcus mastitidis [3] Trypanosoma cruzi [9] Trypanosoma lewisi [9]

TYROTHRICIN

[306]

Bartonella bacilliformis and Leptospira icterohemorrhagiae are not affected by this agent [9]. TOXICITY.—The approximate lethal doses of tyrocidine for 20 gm mice are 0.5 mg i.v. and 1.8 m g i.p. [3]. Intraperitoneal inj of 2 m g is fatal f o r 25 gm mice within 48 hr [7], Fatal doses of tyrocidine result in respiritory death [3]. Oral administration of large doses is nontoxic [3]. The M T D for mice is also reported to be more than 1,000 mg/kg: p.o. or s.c., 20 m g / k g i.p., and 1.25 m g / k g i.v. [10). EXPERIMENTAL CLINICAL RESULTS. —Tyrocidine protects mice against pneumococci infections when given i.p. but is less effective in this respect than gramicidin. It is ineffective p.o., i.p., s.c., or i.v. against Kleb. pneumoniae and Salm. aertrycke infections in mice [7]. See also TYROTHRICIN. See [1] Hotchkiss and Dubos, 1940a; [2] Hotchkiss and Dubos, 1941; [3] Hoogerheide, 1944; [4] Hotchkiss, 1941; [5] Rammelkamp and Weinstein, 1941; [6] Heilman and Herrell, 1941; [7] Dubos and Hotchkiss, 1941; [8] Dubos, 1940; [9] Weinman, 1943; [10] Waksman, 1945. tyrothricin, a mixture of two antibiotic substances, gramicidin and tyrocidine, isolated f r o m the culture medium of a Bacillus sp. [1], later identified as B. brevis [2]. A protein-free preparation may be obtained by adjusting the whole culture to pH 4.5 to precipitate the cells and active material, extracting the active fraction f r o m the precipitate with acid acetone, and removing the acetone by distillation. The residue is taken up in water containing hydrochloric acid and the precipitate desiccatcd in vacuo, washed with ether, dissolved in 95% alcohol, and reprecipitated several times. The yield is a grayish-white powder insoluble in chloroform, sulphuric ether, petroleum ether, benzol, toluol, and water, and soluble in acetone, alcohol, dioxane, pyridine, and glacial acetic acid [3]. Tyrothricin does not dialyze through collodion membranes [1], It is not inactivated by pepsin [1], trypsin [1]. chymotrypsin [1], serum [4], or ascitic fluid [4], More recently it has been determined that the presence of 5cfo horse serum has a deleterious action on the potency of tyrothricin [5]. The activity is not affected by heating to 90 5 C. for 10 min at p H 2 or 9 [1]. An alcoholic solution of the protein-free material retains its activity f o r at least 3 mo at rm. temp. [3]. Tyrothricin is hemolytic for human and rabbit red blood cells; this action is due primarily to the tyrocidine content of the mixture [6]. SPECTRUM.—Tyrothricin is effective chiefly against gram-positive organisms [7], It is both bacteriostatic and bactericidal, and in some instances bacteriolytic as well [1]. The agent is effective in vitro against the following organisms: Diplococcus pneumoniae [1] Hemophilus ducreyi [8] Hemophilus influenzae [8] Saccharomyces cerevisiae [1] Staphylococcus aureus [1] Streptococcus hemolyticus [1] Streptococcus viridans [1] Tyrothricin is further reported to inhibit the growth in vitro of the following organisms in the concentrations shown [19]:

Organism Concentration Actinomyces scabies 1:80,000 Bacillus subtilis 1:1,280,000 Bacterium aroidae 1:10,000 Bacterium carotovorum 1:40,000 Bacterium tumefaciens 1:80,000 Corynebacterium michiganense 1:5,120,000 Corynebacterium sepedonicum 1:10,240,000 Gloeosporium musarum 1:5,000 Leuconostoc sp. 1:80,000 Phytophlhora erythroseptica 1:5,000 Pseudomonas syringae 1:5,000 Rhizoctonia crocorum 1:5,000 Rhizoctonia solani 1:20,000 Sclerotinia sclerotiorum 1:20,000 Stereum purpureum 1:5,000 Verticillium dahliae 1:5,000 Xanthomonas begoniae 1:40,000 Xanihomonas campestris 1:80,000 Xanthomonas malvacearum 1:160,000 The following are partially inhibited in vitro at concentrations of about 1:5,000: Alternaria citri, Botrytis cinerea, Byssochlamys fulva, Cladosporium herbarum, Claviceps purpurea, Fusarium avenaceum, F. culmorum, Myrothecium roridum, Penicillium digitatum, Pythium ultimum, Trichothecium roseum [19], Pityriasis versicolor is reported to be "not very sensitive" to tyrothricin [9], Tyrothricin is without effect in vitro on the following organisms: Bacillus polymyxa [19] Escherichia coli [1] Hemophilus parainiluenzae [8] Klebsiella pneumoniae [1] Penicillium expansum [19] Pseudomonas marginalis [19] Salmonella paratyphi [1] Salmonella typhi [1] TOXICITY IN ANIMALS.—In 20 gm mice the approximate lethal doses of tyrothricin are 1.6 mg i.p. and 0.1 mg i.v. Much larger doses are tolerated p.o. [10] It is also reported that the maximum tolerated dose in mice is more than 1,000 m g / k g p.o. and s.c., 10 m g / k g i.p., and 1.2 m g / k g i.v. [11], In chronic experiments the M T D for adult mice is 0.8 mg p.o. three times a day for 10 days [12], Adult rabbits survive single i.v. injs of 0.6 m g / k g [13]. In dogs, 10 daily i.v. injs of 0.2 m g / k g each have only slight toxic effect, but 0.4 m g / k g results in death of most of the animals before 10 injs have been given. Daily inj of 0.3 m g / k g is not fatal but it causes acute and chronic changes in the liver, spleen, kidney, heart, and lungs. [14] TOXICITY IN HUMAN BEINGS.—Subcutaneous and i.v. inj produces acute anemia, and topical administration is sometimes irritating to the skin [15]. A single inj of 200 mg into an infected pleural cavity was without adverse effect [10], EXPERIMENTAL CLINICAL RESULTS.— Single intra-abdominal injs of 2 mg suffice to protect a significant proportion of mice against pneumococci but are ineffective against Kleb. pneumoniae infections [4], Three daily doses p.o. of 0.4 mg each are very slightly effective against Strep, hemolyticus and type I pneumococcus infections in mice but are somewhat more beneficial in types II and III pneumococci infections [12]. Oral administration is

[307] without effect on the Lactobacillus acidophilus population in the feces of mice. This is thought to be due to the destruction of the activity by digestive juices [16], Tyrothricin has also been found ineffective against meningococcic infections in mice, but this failure may have been due to inactivation by the mucin in which the infecting organisms were administered [17]. In rabbits, 15 daily doses of 2 mg/kg [12] or 0.1 mg/kg [13] are completely ineffective against acute testicular syphilis.

Local administration of tyrothricin in Trichomonas vaginalis infections has marked beneficial effect. Relapses occur, however, and do not respond to further treatment with tyrothricin [18]. See [1] Dubos, 1939a; [2] Dubos and Hotchkiss, 1941; [3] Dubos and Cattaneo, 1939; [4] Dubos, 1939b; [5] Reedy and Wolfson, 1949; [6] Weinstein and Rammelkamp, 1941; [7] Dubos, 1939c; [8] Beeson, 1946; [9] Gate et al., 1948; [10] Hoogerheide, 1944; [11] Waksman, 1945; [12] Kolmer and Rule, 1946a; [13] Kolmer and Rule, 1946b; [14] MacLeod et al., 1940; [15] Long, 1948; [16] Weinstein and Rammelkamp, 1941; [17] Downs, 1943; [18] Weinman, 1943; [19] Gilliver, 1946.

VETERINARY CLINICAL RESULTS. — Instillation of tyrothricin into the udder of cows with mastitis due to Strep, agalactiae has been found to be very beneficial [10]. CLINICAL RESULTS.—The following conditions have responded satisfactorily to topical treatment with tyrothricin: abscesses [10], em-

The crystals occur as yellow needles up to 1 in. long [3], SPECTRUM. — In dilutions of 50 micrograms/cc and less, usnic acid inhibits Mycobacterium tuberculosis avium, Myco, tuberculosis bovis, Myco, tuberculosis hominis, pneumococci, Staphylococcus aureus, and Streptococcus hemolyticus. The following are not inhibited by dilutions of 50 micrograms/cc: Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella aertrycke, Salm. typhimurium, Shigella spp., and Shig. sonnei [3]. TOXICITY.—In 25 gm mice s.c. injs of 2 mg are fatal, but doses of 1.5 mg are without

effect. Two or three s.c. injs of 1.25 mg given at intervals of 6, 22, or 24 hr are not lethal. In 250-350 gm guinea pigs, two s.c. injs of 30 mg, given 24 hr apart, are lethal, but three daily s.c. injs of 20 mg each are not [3]. It is also reported that the LDso for mice is 7 mg/10gm s.c. and 0.25 mg/10gm i.v.

It is slightly better than streptomycin at 40,000 units per day in guinea pigs with tuberculosis (Steenken). At 4 mg/day in guinea pigs with tuberculosis, viomycin nearly tripled their life span as compared with controls. A neurotoxic effect was noted in cats given 100 mg/kg/day, and in dogs there was renal damage at 100 mg/kg/day. At 50 mg/kg/day, dogs seemed to tolerate the drug satisfactorily (Hobby). In human beings 2 to 2.5 gm/day in divided doses given twice daily has been administered to tuberculous patients who had relapsed after para-aminosalicylic acid or streptomycin and who were considered poor risks. At the time of the report, no effect had been observed in two patients after 52 and 58 days; in a third kept on the drug for 72 days the fever never dropped; in a fourth, fever returned after 121 days; and in a fifth, the drug was still being administered after 145 days. In this series there was no vestibular, auditory, or renal damage. The eosinophile count, however, was down 33%, and there was, in addition, some change in electrolyte balance (Muschenheim). See Minutes of the Ninth Streptomycin Conference, 1950. vtridin, a crystalline antifungal substance elaborated by Trichoderma viride. The active material is obtained by extracting the culture filtrate with chloroform, evaporating the extract in vacuo, and crystallizing from ethanol. The crystals are colorless, rodlike prisms which decompose without melting at 217°-223°C. and which are almost insoluble in ether and camphor. Aqueous solutions are unstable except at a low pH. Viridin does not contain nitrogen, sulphur, or halogens. SPECTRUM.—Viridin prevents germination of the conidia of Botrytis allii at 0.005 micrograms/cc. Fusarium spp., Trichothecium roseum, and Cephalosporium spp. have about the same order of sensitivity. Concentrations of 3-6 micrograms/cc are required to inhibit some spp. of Aspergillus and Penicillium. Viridin is not markedly bacteriostatic. See Brian and McGowan, 1945.

xanthomycins A and B, two yellow antibiotic substances o b t a i n e d f r o m an unidentified Streptomyces designated as Streptomyces 94. Xanthomycin A has been obtained as the crystalline reineckate from which the hydrochloride derivative can be synthesized; xanthomycin B has not yet been prepared in crystalline form.

The reineckate of xanthomycin A occurs as long orange needles. The m.p. is 165°-170°C. (decomp.) and the empirical formula, C38H57 NiiOnS4Cr. It is insoluble in cold water and soluble in warm methanol and in acetone. Both xanthomycins are stable in acid solution and unstable at pH 6. There is no loss of activity in 3N hydrochloric acid at rm. temp, for 1 hr, a 90% loss when heated to 100°C. for 25 min at pH 6, and only 14
